Major Barbara Undershaft Timeline and Summary

Barbara starts out super idealistic and enthusiastic about her job at the Salvation Army. Also, she seems to be quite good it.
She becomes disillusioned when the Army's financial troubles translate into their accepting money from her father (an arms dealer) and a whisky distiller named Bodger. In her despair, she relinquishes her Army badge to her father, wondering if she'll ever even be able to pray again.
After seeing the family factory and chatting more with her dad and the others, she comes around to the belief that she can still do a lot of good, even while recognizing the necessity of working with men like her father.
